With the launch of the new 2011 BMW 5-Series Sedan this May, for the first ever BMW’s entire lineup will be equipped digital HD Radio as standard. For anyone unfamiliar with HD Radio, superior sound quality is one of its significant benefits, along with access to thousands of channels including exclusive HD2 and HD3 channels (added sub-channels spun off the main radio frequency).

BMW was in fact one of the first to offer HD Radio as an option, beginning in 2006, and has offered the feature as an option across all model lines since 2007. BMW has enabled HD Radio's built-in data capabilities for real-time traffic information features in its vehicles.

Today, there are over 2,000 radio stations in the U.S. broadcasting HD Radio, more than 1,100 of which are airing the newer HD2 and HD3 channels. For a complete listing of HD Radio stations, check out www.hdradio.com.

A number of rival automakers have also announced plans to expand HD Radio capability in their vehicles, including German rivals Audi and Volkswagen.
